RoLLs Dresden, Germany Application July 17, 1934, Serial N0. 735,634 In Germany July 24, 1933 15 Claims. (Cl. 131-42) 'I'his invention relates to machines for making cigar rolls, more especially to a machine of simple construction in which all devices imitating or replacing handwork are controlled by suitable levers all of which are actuated from a common cam-disk or drum in well-timed operation.

The machine according to the present invention eiects the wrapping of the ller by means of the well-known rolling belt and rolling table, as well as the previous shaping of the ller, the setting of the nished roll in view of the wellknown pressing mold and the introduction of this roll into one of the parallelly disposed chambers of the opened pressing mold, this pressing mold moreover being stepwise advanced after each charging of a pressing chamber.

According to the invention this object is realized by providing in the machine a lever by means of which the pre-shaped portion of filler is conveyed above the slack of the rolling belt, a second lever controlling the means for rolling the tobacco and opening, after the rolling operation is completed, a guide or device for holding the roll and iinally a. third lever transferring the ller kept in position into the slack and at the same time pressing the roll kept in the guide into the roll-pressing mold which is carried into the corresponding position by the lever controlling the rolling-belt. All the levers are controlled by one and the same cam-drum.

I am aware that some of the elements constituting the combination hereafter claimed have already been used separately in machines for making cigars. What I claim is the new combination of the lever-controlled mechanisms by which handwork is replaced in a most simple manner.

The invention is illustrated by way of example in the annexed drawings of which Fig. 1 is a front elevation,

On the plate I supported by the frame 2 the rolling table 3 is provided on which the rolling belt 4 is placed. A cavity 3 is provided in the rolling table into which cavity the portion of 30 tobacco to be rolled is pressed. This tobacco portion is measured by means of a molding-box 5 (Figs. 6, 7). This box, mainly consisting of a thick wooden board provided with a corresponding cavity 5', is secured by screws 'I to a swing 35 lever 6 secured to the top end of the shaft 8 journaled at 9 and I I). The bearing box 9 is mounted in the plate I, whereas the bearing I0 forms part of the bracket I0 mounted on the plate of the table. At the bottom end of the shaft 8 a small cog-wheel I2 is secured engaging a rack I3 (Figs. 8, 9). The latter slides with a prolongating bar I4 longitudinally in a guide I5 screwed from belowr to the plate I, the rack I3 engaging with its projection I3' a recess I4 45 formed in the bar I4. A pin I6 is provided on the rack I3 and a pin I1 on the bar I4. These. two pins are engaged by a spiral spring I8 which tends to bring the rack and its prolongation into the position shown in Fig. 8. By this connection of the rack I3 with the prolongation I4 no undesired play between the respective members arises even after the machine has been used for a long time. I-Iowever', if a play occurs after some time between the cog wheel I2 and the teeth 5 5;

of the rack I4, no slip will result because the spring I8 always acts to maintain a contact between the engaged elements at one side at least.

The roll I9 mounted on the bar I4 is encompassed by the U-shaped end 2D of the lever 20 (Fig. 6). The lever 20 is secured on the shaft 2| journaled in the bracket 22. Furthermore on the shaft 2l a lever 23 is mounted the end of which bears the roll 24. A spring 21 fastened at 28 engages the arm 20. Under the action fof the spring 21 the roll 24 is pressed against the cam 26 provided on the cam-drum 25.

The winding roller 29 coacting with the rolling belt 4 is journaled with its ends 29 in eyes 39' provided at the upper ends of two swing levers 30 (Figs. 13-16) The latter are secured by means of hubs 392 on a shaft 3| journaled in small bearing brackets 32 and 33 (Fig. 2).

The rolling belt 4 is placed over the guiding roller 34 and secured at 35 and 36 (Fig. y13). A tension or tightening roller 31 journaled at vthe levers 38 (see especially Fig. 14) engages the slack or loop lying between the point of fixation 35 and the guiding roll 34. The levers 38 are connected by a bridge 39 and are supported by pivots 40 -and 4I secured to the frame of the machine. The controller 42 connected by a screw 43 with a lever 3B, is mounted on the pivot 4I. The swing arm 42 is on its lower side at 42 shaped to form a curve (Figs. 13 and 15). The roll 45 provided on the projection 44 of one of the levers 39 coacts with the said curve 42. The end `42? of the swing lever 42 coacts with a pawl 41 subjected to the tension Aof the spring 46 whereby this swing lever is kept in the position shown in Fig. 13. The pawl 41 is fulcrumed in the pivot 48 secured in the frame of the machine. Furthermore a two-armed lever 49 is mounted on the pivot 40 which lever carries at its one end 49 the set screw y50 with the counter-nut 5I. The left-hand arm of the lever 49 is shaped on its lower side 494 to form a curve. The end 492 of this arm vengages in its idle position a vpin 52 provided onthe frame of the machine.

The swing levers 3D are connected by the pivot 53 engaged by the link 54 (Fig. 1). The latter encompasses the pivot V55 .provided at the free end ofthe lever 55. The lever 55 is fulcrumed at 51on the frame of the machine and engages with the roller 58 provided thereon the cam-groove 59 provided -in the cam-drum 25.

The here described device operates as follows:

When the winding roller 29 is in the position shown in Fig. 13, the right hand end of the rolling belt 4 slacks as shown in the drawings forming a loop. Now the tobacco portion from which the roll is to be formed is pressed down into the cavity 3 of the rolling table.

Hereupon the swing levers 39 are swung by means of the cam-drum 25 to the left hand in Fig. 13. As soon as in this way the winding roller 29 has attained the position shown in Fig. 15, the tobacco portion has been lifted from the cavity and is kept in the loop formed behind the winding roller 29. As the cavity 3' is madeconsiderably deep to prevent the tobacco or the like from scattering out, an excess or rolling belt is present behind the loop so that the tobacco on the rolling table could not be duly formed to a roll (see Fig. 15). For this reason the rolling belt must be stretched or tightened by the tension roller 31 so as tokeep the tobacco portion'together by the loop formed in the prescribed manner as shown by full lines in Fig. 15. This is effected by the roller 6l provided'on'the projection 60 of the swing lever 30 which coacting with the cam portion 493 of the swing lever 49 swings the latter into the position shown in Fig. l5. Hereby the lever 42 connected with the lever 38 is pressed against the action of the spring 45 out of the range of the link 41.

Hereby-the tightening roller 31 has been carried down so that the rolling belt 4 has undergone a corresponding tension as shown in Fig. 15.

' Whilst hereupon the roller 5I is rolled along the cam portions 494 substantially lying between the fulcrums of the levers 39 the tobacco portion is shaped to a roll by enveloping the same with the inside wrapper in the well known manner and is nally thrown out at the end of the rolling table.

While the winding roller 29 is returning (viz. moved `to the right hand in the sense of Fig. 16) the roller 6I runs anew rst along the cam portion 494 and finally after having met the cam portion 493 causes the lever 49 again to swing into -its initial position, the end 492 `engaging the pin 52. At the end vof the right hand movement of the levers 39 or the winding lroller 29 the roll 45 meets the lcam portion 42' lifting the latter while tightening the rolling belt and finally placing it lbehind the rest of the swinging lever 41.

.In the modification here described it is assumed that the cam portion is shaped concentric to the fulcrum of the swing levers 3i). In this way the corresponding cam portion 494 may -be made to project vmore and more towards the end of the swing lever 49, as shown in Fig. 17 by dotted lines. In this case the tension of the rolling belt would be increased during the rolling operation by correspondingly swinging the lever 49. However thefcam portion 494 may also be shaped according to the dash-and-dot lines in Fig. 17. In this case the tension of the rolling belt would be `decreased toga certain extent during the rolling operation. Whether the tension during the rolling operation is to be increased or decreased depends upon the quality of the tobacco and the form of the roll used. In any case the present invention affords the possibility to adapt Ythe cam portion 494 to different conditions.

A pair of jaws 92 and S3 is provided beneath the left hand end of the rolling table 3, the jaws being shaped according to the shape of the roll (see especially Fig. 19) Whereas the jaw 62 is rigidly secured to the frame by an arm 64, the jaw 63 is fixed to the upper ends of two swing levers 65 mounted on the shaft 99 (Fig. 18). The latter is journaled in a small bracket which is secured tothe plate i of the table. Upwardly projecting members 65 shaped to form abutments (552 are provided on the levers 65. The two ends of the winding roller 29 meet these .abutments after the roller has nearly reached its left hand end position (with reference to Fig. 1). Thereby the levers 55 are swung against the tension of two springs 61 engaging them in such a manner that the jaw 53 is moved apart from the jaw 62 and the roll falling out of the rolling belt may easily drop into the space between the jaws.

Beneath the jaws a bifurcated fork 68 is provided which when the roll drops `from above between the jaws 92 and 53 is in the position iown in Fig. 29 and thereby prevents the roll from falling from between the jaws. VThis `fork 93 is secured by means of screws 69 on a carriage longitudinally slidable below the rolling table 3.

yIn the vcarriage 10 the block 1| is rotatably mounted which is engaged by the bifurcated end 12 of the lever 12. The lever 12 may be swung on the shaft 13 which is supported by a small bracket secured to the table I. gaging the free end 122 tends to swing the lever 12 in the direction of the arrow (Fig. 22). A freely rotatable lever 15 is provided on the shaft 13 carrying a projecting arm 15'. In the arm 15 a set screw is provided serving .as an abutment and projecting into the range of the arm 122. A spring 11 engaging the lever 15 at 152 and the lever 12 at 123 tends to move the two levers 12 and 15 against one another in such a manner that the set screw 15 comes into contact with the arm 122. A projecting member 3E)5 is provided on one of the swinging levers 30 carrying the roll 18. The latter projects into the plane in which the lever 15 is swung.

A pawl 80 is linked to the carriage 10 by means of the pin 19, this pawl carrying at its rear side a prolongation contacting the carriage 10, whereby the downward movement of the pawl 80 is limited (Fig. 18).

When the swing levers 30 carrying the winding roller 29 are in their right-hand position in view of Fig. l the carriage 10 is in the position shown in Fig. 18. Now when the swing levers 30 are swung to the left hand side in the sense of Fig. 1, the roll 1S meets the lever 15 before the swing levers 30 reach their left hand end position and the lever 15 is swung into the position shown in Fig. 22 carrying with itself the lever 12. Hereby the carriage 10 is moved from the position shown in Fig. 18 into the position shown in Fig. 22, the pawl engaging the pressing chambers SI of the pressing molds 8| advancing the pressing molds 8| guided beneath the rolling table 3 between guiding racks 83 by one step, that is to say the pressing molds 8| are .advanced by one section of the pressing chamber 8 I in the direction of the arrow shown in Fig. 22, so that the next empty pressing chamber takes the position beneath the channel formed by the jaws 62 and 63. At the same time the fork 58 secured to the carriage has been displaced so that its prongs are beneath the jaws 62 .and 63 and receive the roll dropping from the rolling belt.

Now when the swing levers 30 carrying the Winding roller 29 are anew swung backwards to the right hand side, the roll 13 again releases the lever 15 so that the latter may swing downwards under the action of the spring 14. Hereby the upwardly projecting abutments 65 of the levers 65 are released, the jaws 62, 63 are closed, and at the same time the fork 63 is again withdrawn with the pawl 89 into the. position shown in Fig. 18. The roll is now kept exactly above the empty pressing chamber 8|', the jaws 62, S3 being slightly compressed. Y

The roll is projected by the piston 84 out of the channel formed between the jaws 52, 03 into the pressing chamber thereunder (Fig. l). The lower end 84 of the piston 84 is shaped in accordance with the form of the tobacco roll. In order to permit of the manufacture of cigars of different size by this machine, the lower part 84 of the piston is made exchangeable. 'I he piston 84 is shaped to form a slider slidable and fixable in a guide 85, the screw 86 serving for adjusting and the screw 81 for fixing. The guide 85 is provided on a cross-member v88 carrying the piston 89 for projecting the tobacco portion from the molding-box 5 into the pressing-cavity 3. This piston is likewise made exchangeable according to the exchangeability of the molding-boxes 5.

The cross-member 88 is provided with two up- A spring 14 en- 'in the plate I.

wardly projecting guide bars 90 and v9| which can be vertically shifted sockets 92 and 93. The sockets are formed on a frame-arm 94 mounted on the plate I. bifurcated and carries the pivot 95. The roller 96 supported by the pivot 95 is encompassed by the bifur-cated end of the lever 91 which is secured to the shaft 98. The latter is journaled in an upwardly projecting part 94' of the frame arm 94 and carries at its other end the lever 912. The free end of the lever 912 is engaged at 913 by the governing rod 99, the lower end of which is connected by the pivot with a lever |00. The hub IOI of the lever |00 is journaled on the shaft |02 carried by a bearing bracket |03. To the hub |0| a lever |04 is secured engaging with its roller the cam groove of the cam drum 25.

The drive of the machine is effected by an electro-motor |81 mounted on a plate |08 arranged under the plate I of the table. (Fig. 3). The plate |08 is supported by arms |09 secured to the lower side of the plate I. A Icord I is led over the pulley |I0 of the electromotor and runs over the pulley I I2. The latter is mounted on a shaft |I3 journaled in a casing ||4 and The upper end of the bar 90 is carrying the worm ||5. The latter engages the l worm wheel IIS mounted on the box ||1 (see also Fig. 25). The box ||1 is freely journaled on the shaft I I9 and carries at its left hand end the disk ||9 which is provided with a circular row of bores I I9' concentrioally arranged around the shaft I I8. A disk is adjointed to the disk ||9, the hub |2| being non-rotatably connected with the shaft I I8 by a feather or key |22. From the hub I 2| projects a member |23 in which a bore |24 is provided penetrating also the disk |20. Into this bore the lost motion bolt is inserted which is pressed to the right hand in the sense of Fig. 25 under the action of a press spring |28. Into the losI'l motion bolt |25 a pin |21 is screwed which projects through a recess |23 provided in the member |23. A roller |28 is mounted on the end of the pin |21.

When the bolt |25 takes the position Vshown in Fig. 25, its front end engages one of the bores |I9 so as to coupley the two disks ||9 and |20 and therewith the worm wheel ||6 with the shaft H8; The latter supported by bearing brackets |29 and |30 secured on the plate I 08 is secured to the cam cylinder 25.

When the motor |01 is running the shaft ||8 is turned, with the cam drum 25 mounted thereon, in the direction-of` the arrow shown in Fig. 1f4 As soon as the roller |28 comes into the range of the sloping surface |3I, the roller |28 rises on the. sloping surface I 3| as shown in Fig. 28. Hereby the bolt |25 is moved to the left hand side in the sense of Fig. 25. Thus the end of the bolt |25 projecting into the eld of the disk |I9 is withdrawn so that the two disks IIS, |20 are discoupled. Therefore the disk |I9 continues to turn with the worm wheel 6, whereas the disk |20 with the shaft ||8 in the cam cylinder 25 stops.

The sloping surface |3| is disposed at the free end of the lever |32 which is secured on the shaft |33 by a pin |34. On the shaft |33 which is carried by a bearing bracket arranged beneath the plate of the table the lever |38 is v secured carrying at-its free end the presser button |31 upwardly projecting through a hole A spring |38 engaging the lever |32 at |32 tends to keep the lever |32 in the position shown in Fig. 1. The spring |38 is suspended at |39 on the pin |39 secured to the table To prevent the bottom I of the molding box 5 when swinging around the shaft 8 from being pressed down on introducing the tobacco a small block |49 is secured to the free end of the bo-ttom plate and the plate |42 is screwed by means of the screws M! on the said block (Figs. 6, 7). The plate |f2 overlaps with its end |42 the end of the swing arm l5 as shown in full lines in Fig. 'l and in the manner shown in Fig. 6. In this means the plate is absolutely prevented from being pressed down from the swing arm 8 when introducing the tobacco. The block |49 is provided with the bo-re |439 into which a bolt |56 being exposed to the action of the press spring |43 is inserted. The end |||22 of the plate |42 is bent down at a right angle and the spring |43 rests on it. On the other hand the bolt |44 is pressed against the edge 5 bent to a circular arch of the swing arm 6 whereby a frictional connection between the bottom plate il and the swing arm B is effected. As shown in Fig. 'l the arc shaped edge 6 is continued on a projecting member 62 of the swing arm.

The device operates as follows:

After the operator has duly lled with tobacco the cavity 5' of the molding box 5 i. e. after he has introduced so much tobacco into the cavity 5' that after slight pressing down. the cavity is lled with tobacco as uniformly as possible, and after the operator has placed an inside wrapper U on the rolling belt as shown in Fig. 13, he may start the machine by pressing down the button |31. Hereby the levers |32 and |36 are swung against the action of the spring |38 in such a manner that the sloping surface |3| is pressed ont of the scope of the roll |28 as shown in Fig. 27. Now the bolt under the action of the spring |26 may catch a just passing bore i9 so that the worm wheel i9 which is continuously rotated by the electromotor is coupled with the shaft H8 and thereby with the cam drum 25. Therefore the latter is set in motion in the direction of the arrow shown in Fig. 1. I-Iereby first the linkage 20, 23 is swung under the action of the spring 21 in such a way that the shaft 8 is turned and the swing arm 9 carrying the molding box 5 passes from the position shown in full lines into the position shown in dotted lines in Fig. 7.

During this swinging operation the utmost end cf the bottom plate Il provided with the small block |40 meets the .abutment |45 provided on the frame of the machine. By this abutment the bottom plate is retained in the position shown in dotted lines in Fig. 7, whereas the swing arm carrying the molding box 5 takes its end position in which the swing arm with the: projecting lug 53 touches the abutment |135. In or-der to attain in any case that the swing arm surely arrives in this end position, i. e. the cavity 5 of the molding box e-iactly takes the position above the cavity 3 of the rolling table the cam 26 is so shaped that the levers 29, 23 are moved somewhat farther than necessary, the required expansion of the linkage being effected by the two parts I3, I4 moving a small distance towards one another against the action of the spring I8 of Fig. 9. By retaining the bottom plate in the position shown in Fig, '7 in dotted lines the cavity 5' is open in the downward direction and now the piston 89 may be put into action. This is effected from the lifting curve |93 which causes the rod 99 to go upwards and to carry the cross-member 88 downwards. Thereby the tobacco portion T pressed into the cavity 5 is pressed into the cavity 3 of the rolling table taking with it the rolling belt 4 and the inside wrapper U. It may be noted that this is effected whilst the rolling belt is completely released (see the lifted position of the tightening roller 3l and the free slack of the rolling belt forming a loop in Fig. 13)

Now the swing arms which during these operations took the position shown in Fig. 13 are swung from the left hand up to the position shown in Fig. 1. An intermediate position is shown in Fig. 15. Here the tobacco portion T has just been lifted from the cavity 3' and is located in the loop formed behind the winding roller 29. Now while the latter moves forward to the left hand in the sense of Fig. 15 the tightening roller 31 is actuated by the above described means. When the swing arms 39' and the winding roller 29 have approx'mately reached the position shown in Fig. 18 the roll 78 strikes the lower curve-shaped side '|53 of the lever 'l5 the latter being swung against the action of the spring 'ld while the swing arms 30 go farther to the left hand. Hereby the carriage is displaced in the direction of the arrow shown in Fig. 18. This however results in the pawl 8G, engaging the empty pressing chamber 8|', displacing the pressing mold 8| in such a manner that the said pressing chamber takes a position under the channel formed between the jaws 62 and 63. Shortly before the motion of the swing levers in the direction of the arrow shown in Fig. 20 is completed, the ends of the winding roller 29 meet the upwardly projecting abutments whereby the levers 65 are swung up to a position shown in Fig. 20. Hereby the jaw 93 is removed from the jaw 52 so that the tobacco portion T and the inside wrapper U forming together the roll W when projected from the rolling belt may freely fall between the jaws where it is first retained by the prongs of the fork |58.

On swinging backwards the levers 30 to the right hand in the sense of Fig. 1 rst the abutments 55 are released again by the winding roller 29 so that the lever 55 under the action of the spring G'l may anew advance the jaw 63 toward the jaw 62 and now the roll W is kept clamped between the two jaws. At the same time also the carriage 19 is again carried back into the position shown in Fig. 18 so that the prongs 68 cease to obstruct the channel formed s between the jaws 62 and 63.

During the operations just described the swing arm E has been swung back into position shown in full lines in Fig. '7. Hereby, before the swing arm has reached its initial position the vbottom plate strikes an abutment |41 provided on the bearing bracket Hl' so that the bottom plate again closes the cavity 5.

As soon as the cam drum 25 has made a full turn and therefore the controlling elements deriving from it have once fulfilled their respective operations, the roll |29 again strikes the sloping surface |3| whereby the disks H9, |29 are discoupled and therewith the cam drum 25 is stopped. In the meantime the operator has again lled with tobacco the cavity 5 of the molding box and placed a new inside wrapper on the rolling belt. However the machine cannot be started again before the operator actuates the button |31 whereby at the same time it is warranted that an operator cannot by mistake come into contact with moving elements of the machine.
